A discussion or debate which involves deciding which type of asian woman is hottest, most dateable or best in bed. Facts in these arguments are often gathered from internet porn or urban legend, if lacking in research you can simply make shit up.
Joe: DUDE, Japanese girls are open to do anything in bed. For fuck sake, they have blowjob competitions on TV.
Bill: Nah man, koreans are the best. They're great and bed and actually enjoy cleaning up after you...
You: I'm not having this "top ramen discussion"
